See above the table for the application of each type.
— hub: for support of network access devices that do not support
SSCP, and multiple devices on a single port.

corporate DNS server when the network access points are NSNA
network access points and Filters only enforcement is configured.
— standard: for standard DHCP services that conform to RFC 2131
for DHCP relayed messages.
Each type has a set of configuration options associated with it. For
information on these options, see

As a minimum, you must configure Option 3 (Default Router), Option 6

specified in seconds.
The values set at this level of the DHCP menus are applied globally to all

the global values when specific DHCP settings are configured. See
